T all whom it may conce mc: r

Be it known that I, DAVID-M. GRAHAME a citizen of theUnited States,residing at Bordulac, in the county ofFoster and State companying agrainharvesting meCl1tI11SD1 of NorthDakota, have invented certain newand useful Iinprovementsinv Apparatus for Forming and DepositingStacksof Grain and the like, of which the follow-ingiis a"specification, reference being had therein to.

the accompanying drawing.

The invention relates to stacking apparaa;

tus-adapted to're'ceive grain as it is out, or otherwise formfthe sameinto stacks and deposit the latter upon the ground for the curing of thegrain berries, such curing process being more particularly set forth in;my application Serial No. 47,256,;fi1ed Aug.25, 1915. 1

"The present invention is directed par ticularly to the easy and'smoothdeposit'of the stack from the former while the latter is in motion,ordinarily attached to or ac and Without disarranging or misshaping theformed stack. By so depositing the stack I am also enabled to leave itat a greater distance fromthe standing grain so as to leave plenty ofroom for the cut-f ting of the same.

comprises a'stack former having a wheeled support, upwardly extendingwalls which shape the exterior of the stack," means for depositing thestack,' and a substantially vertical pivotal support whereby the stack.v former may turn in substantially horizontal planes as may be requiredtowithdraw itt smoothly from the stack as the latter is I r I wheels- 1,and anaxle Qcarried bysaid advantages which may be incident 't'o'the useof the improvements, the invention consists in the parts andcombinations thereof.

hereinafter set forth andjclaii'ned, with the understanding that theseveral-necessary ele-' ments constituting the same may be varied inproportions and arrangement wi1thout p I cutting the grain to bestacked.

departing from the nature and scope of the invention. In order. "to makethe invention more clearly understoodthere are shown inftl ie'accompanying drawings means for carrying the same into practical effect,without limit ing the improvements, in their useful applicat-ions,' tothe particular constructions of said mechanism.

The side walls 7 are constructed to incline plate .19, thelatter beingattached to the "away from each other; in thefdirection to Ward the endgate 8 so that the formed-stack readily frees itselfjfrom said sidewalls as 'itis being deposited.- The bottom of the stack.,former shown,at lOj comprising stack-supporting"rods" or metal pipes 11 which extendin the direction of dumping. At, aboutthe median line of'said bottom vit'is provided with pivots 12 (Fig. 3) on which the'bottom may tilt forthe deposit of .a stack, its inner end rising and 'its outer declininguntil the outer vends of the rods 11 trail uponthe ground as the stackslides but of the former and off from the bottom.

- @Thestack former is mounted on a substantially ,vertical; axis sothatits delivery end mayturn rearward asthestack is de- 7 posited, suchturning beingefi'ecte'd by. the

retarding of said delivery end when the rodsfll and the end portion of;the stack engage .withqthe ground." Suchv a pivotal 4 5,

axis is or may belformed as illustrated, 17 beingja vertical; pivotwhich unites upper 21 and'lower bearing plates 18 and 1.9, in the natureof. a fifth Wheehthe plate l8 being attached.v to the-lower part of thestack former. frame 1 and adapted to turn on the I wheeled support Y 20is asegmental. guide I attached to the tongue 4 and having upper andlower flanges (Fig. 3) between which runs a roller 21 having a journalbracket 22 which is i attached to the fr ntof-the 'frame'5, where-j lbythe frame is guided in it'sfpar'tial rota-Q tion. and prevented fromtilting.v The rear end of the guide 20, holds the roller '21 from Erearward movement whenthe stack former .isinflnormal grain-receivingposition and at that time any forward turningof the grain, end 'ofithestackformer is prevent'edby a. latch -23 (Figs. sand 5) which-ispivoted,

on the frame 5- and hooks over a pin 2 L fixed on a bracket 25 carriedby the tongue, sothat under such conditions the stack former cannot turnon its vertical pivot.

,The latch 23.is rcleased,to permit the stack former to beturned,by alink 26 which connects the-latch with a lever or treadle 27 on theplatform 13. The latch is pressed downward by a spring 28, and relatcheson said pin when the stack former is turned back to normal positionafter dumping.

The weight of that portion of the stack which is at the outer side ofthe pivots 12,

(at the right hand in Fig. 2) is somewhat greater than the weight of theinner port1on of the stack at the other side of the said pivots,-so thatwhen the tilting bottom 10 is free to turn onthelpivots the stack willbe dumped and will at the same time tened to a portion of the frame'5(Fig. 5).

When the bottom is in normal position the latch 30 engages at the outerside of a post 32 which is rigidly secured to-the front portion of thebottom 10 and extends up to the top. of the stackformer.

braced by an inclined member 33 which is attached to said post at itsupper end and extends down parallel with one of the side The post 32 iswalls 7 and is secured at its lower end to the bottom (Fig. 2).. Thelatch 30 is released by'a hand lever 34 which is adapted to pull thelatch away from in front of the post 32 -whereupon the bottom will tiltunder the weight of the stack as above described.

The. outer, end of'the grain transporting device B is suspended fromapulley 35 rest ing upon aftrack 36. This track is secured to the frame5 on posts 37 which extend upward therefrom, and the rear portion of thetrack is curved concentrically with the vertical axis of the pivot 17,so that thedev ce is properly supported while the stack holder turns onsaid axis. c c

38 is a ground wheel attached to the outer end of the bottom 10 andadapted to trail upon the ground whenthe stack is deposited. Thiswheelmay be a caster wheel as indicated in ig.'1. What Iclaim'is:
